reported on the top line after the air system name for operator information. The ON setting is the
normal setting for each air system.
The mode setting affects the air system in the following ways:
“ON”
Jobs that are recalled from memory will automatically take the air system
to the pressure stored in the job.
“MAN” (manual)
The air pressure will not automatically change when a job is recalled. The
pressure or force setpoint can still be changed by manually entering a
desired pressure setpoint.
“OFF”
The air pressure will not automatically change when a job is recalled. The
Automatic Setups module will not control the air pressure in any way. For
units equipped with an integrated valve with manual fallback, the manual
side will be engaged and pressure can be adjusted through a manual
regulator.
Section 5.2.2 Pressure and Force Setpoints
Pressure can be set in one of two ways. First, if the air system was correctly configured, the
desired force which the pressure is to create can be entered in the “Force Setpoint” row on the air
pressure screen. Second, if preferred, the desired air pressure in psi may be entered into the
“pressure setpoint” row.
For counterbalances, the “Die Weight Set” is the weight of the upper die that attaches to the
slide. (The counterbalance must also offset the weight of the press slide, but since this is a
constant accounted for when the system is configured, only the upper die weight need be
entered). The upper die weight, which is required by OSHA to be stamped on the die, can be
entered in the force setpoint row.
For cushions, the “Cush Force Set” is the amount of “push” that is exerted by the air pressure
times the cylinder area.
Note that pressure, die weight, and cushion force are restricted items as defined in Section 2. The
RUN/PROG key, a user code, or both may be required to change them. If a force setpoint is
entered, the proper pressure in psi will be calculated and applied to the system. Likewise if
pressure is entered, the force setpoint will be calculated and displayed.
Section 5.2.3 Cushion Dump Operation
Cushion dump can occur if the cushion dump input, IN 3, is switch on, 24 V. Wiring of the
cushion dump is explained in Section 3.4.3. If this input is switched on, the cushion dump
solenoid will turn on. If a Type “B” valve is being used for cushion pressure control, the cushion
pressure will go to the minimum value set by the manual regulator (as long as there is shop air
pressure.) If a type “A” or “C” valve is being used, the cushion pressure will go to zero.
